In this work, for the first time poly (benzoquinone) chromium (III) complex (PBQC) was synthesized with a one pot, one step, simple and fast method. This novel polymer was used for modification of graphite paste electrode for electrochemical determination of Mesalazine. Moreover, this novel modifier was characterized by Fourier transform infrared spectroscopy, Field emission scanning electron m...

It is shown that for molecules of Allochromatium vinosum [NiFe]-hydrogenase adsorbed on a pyrolytic graphite electrode the nickel-iron active site catalyzes hydrogen oxidation at a diffusion-controlled rate matching that achieved by platinum.

Boron-doped graphene, synthesized by annealing a mixture of graphite oxide and B2O3, has shown a high conversion efficiency of 6.73% as a counter electrode (CE) for dye-sensitized solar cells, which is better than the Pt CE.

Carbon nanotubes are regarded as promising building blocks for the construction of novel biosensors due to their unique properties like fast electron transfer, high electrocatalytic effect and good biocompatibility. In the present study, the effect of different chemical oxidation’s methods of multi-walled carbon nanotubes (MWCNTs) on the electrochemical behavior of modified graphite electrodes ...

We report new three-dimensional (3D)-nanostructured MoS2-carbonaceous materials in which MoS2 sheets are intercalated between the graphite layers that possess a multiply repeated graphite/MoS2/graphite structure which prevents the aggregation of MoS2 and diffusion of sulfur from carbonaceous materials, enhancing the cycling stability of Li-ion batteries. We developed an efficient and scalable p...

The voltammetric performance of edge-plane pyrolytic graphite (EPG) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (OMZ) in aqueous solution. The results revealed that the oxidation of OMZ is an irreversible pH-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

A Johnson Matthey 287 (JM 287) graphite powder disks sandwiched between two nickel screens was used as working electrodes in 1.0 M lithium hexafluorophosphate in mixed carbonate ester electrolyte. Their intrinsic impedance and lithium intercalation kinetics were determined using several different electrochemical impedance spectroscopy (EIS) protocols. The thermal stability of the electrolyte wa...

carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (vo2+) in aqueous medium. the new ligand was synthesized in three steps with high yield. the optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), and sodium tetra...
